[0010001111]... Hello User... [1001010101]
Here's your answer...
This question is solved this way.
tan 89 = tan (90-1) = cot 1
Similarly, tan 88 = tan (90-2) = cot 2
This happens for all numbers after 45°, except 45°.
The series becomes tan 1 cot 1 tan 2 cot 2...tan 45
Since tan and cot are reciprocals of each other, their product will be 1.
So the whole series is reduced to tan 45, which is equal to 1.
So the answer is option B.
